I have the Nav unit in my new to me 2005. The radio is great, CD changer (in console, as pointed out) is great. I got it from a Honda dealer and I think their detail shop removed the owners manual and nav cds when they cleaned it, sales person of course knew nothing about them. I researched the nav cds. For just under $200 you can get an updated set, but I don't know when they were last updated. You can find older ones on e-bay for $15-20 EACH, but not much good. I debated getting a new nav/stereo/CD unit, but since the CD changer works great and will play CD I burned from MP3s on my computer, I decided to just get a Garmin and leave the factory unit alone. With an SD card, USB drive or Bluetooth input the CD changer is really a moot point though. I wanted a back-up camera and got a Garmin wireless system. It's okay, relatively easy to install (I put the sending unit on top of the wiper bulge in the hatch cover), but don't expect it to be like a factory unit in a newer car. Those are better because they are tuned to the individual car, not a one-size-fits-all. definitely better than no camera, but you still use it in conjunction with your side mirrors.
